791 FXUS62 KMLB 230309 AFDMLB Area Forecast Discussion National Weather Service Melbourne FL 1009 PM EST Fri Nov 22 2024 ...New UPDATE... .KEY MESSAGES... Issued at 228 PM EST Fri Nov 22 2024 - Below normal temperatures linger tonight through Saturday night, with a gradual warming trend forecast Sunday and into next week. - Poor to hazardous boating conditions continue through tonight. - Remaining dry over the next several days, with fire sensitive conditions remaining in place through this weekend. && .UPDATE... Issued at 919 PM EST Fri Nov 22 2024 Noticeably cooler tonight as the west to northwest winds bring colder temps to the area. Temperatures as of 9PM are ranging from upper 40s to low 50s along the coast, and low to mid 50s across the interior, with dew points in the low to mid 40s across east central Florida. Breezy and gusty west to northwest winds earlier this afternoon have diminished this evening to 5-10 mph which will persist through the overnight hours. Dry conditions will prevail tonight with no mentionable rain chances. Temperatures tonight are forecast to be around 10-15 degrees below normal, with clear skies. Overnight lows will be in the low to mid 40s for most locations, with upper 30s in the traditionally cooler locations across northern Lake and NW Volusia counties. Forecast remains on track with no major changes. && .PREVIOUS DISCUSSION... Issued at 228 PM EST Fri Nov 22 2024 Tonight-Sunday...Mid/upper level trough exits offshore the eastern U.S. coast tonight, with sfc high pressure across the central U.S. settling southeast and eventually across Florida Saturday night into Sunday. Breezy W/NW winds this afternoon will diminish to around 5 to 10 mph past sunset, and will continue to transport colder temps into central FL tonight. Temps will be even lower tonight than last night, with lows forecast to be around 10-15 degrees below normal. Min temps will be in the low to mid 40s for most locations, and may even see some upper 30s across normally colder locations NW of I-4, mainly across northern Lake and NW Volusia counties. Wind chill values will be as low as the mid to upper 30s around daybreak Saturday morning. The significantly drier airmass in place will keep skies sunny into Saturday, with highs once again only reaching the mid to upper 60s. N/NW winds will not be as gusty with speeds around 10 mph into the afternoon. Then as high pressure settles in Saturday night, winds become light and variable, with dry conditions continuing and skies remaining clear. This will lead to favorable radiational cooling conditions and allow temps to fall quickly back into the 40s Saturday night. Winds remain pretty light into Sunday, and we will begin to see a warming trend take hold. Highs will be still be just a few degrees below normal on Sunday, but warmer than Saturday, in the low to mid 70s. Lows Sunday night will also be closer to normal in the 50s for most locations, except mid to upper 40s NW of I-4. Monday-Friday...(Modified Previous Discussion) Mainly zonal flow aloft continues through the upcoming work-week. Weak high pressure a mainstay across the area, until the next formidable front forecast to push into central FL late Fri afternoon-Fri night. We continue to keep conditions dry thru the period. The warming trend started on Sun will continue with U70s to around 80F (M70s Volusia coast Mon) for Mon-Wed and low 80s on Thanksgiving Day. Temps may then drop again into Friday depending on timing of frontal passage. Mins in the 50s for much of the interior with some L60s gradually returning E of I-95 and possibly M-U60s by Thu morning for immediate St. Lucie/Martin counties. Generally light winds thru the period. && .MARINE... Issued at 228 PM EST Fri Nov 22 2024 Tonight...Wind speeds will diminish slightly but still remain elevated out of the NW up to 15-20 knots into tonight, with seas up to 6 to 7 feet offshore. Nearshore, seas will be around 3-5 feet. The Small Craft Advisory will continue over the offshore waters through late tonight, but will be allowed to end at 4 PM this afternoon nearshore. However, small craft should still exercise caution over these waters through this evening. Sat-Tue...(Previous Discussion) High pressure builds into the area through the extended with continued dry conditions and much lighter winds as the pressure gradient relaxes. Poor conditions (4-6 ft seas) initially in the Gulf Stream early on Sat, with seas continuing to subside thru the weekend and early next week with generally favorable boating conditions. However, hazardous conditions may develop near inlets during the outgoing tide sometime on Sun and continuing into early next week as an increasing (ENE/NE) long period swell (12-14 seconds) is forecast. && .AVIATION... (00Z TAFs) Issued at 713 PM EST Fri Nov 22 2024 Very VFR and favorable flying conditions prevail through the TAF period. Northwest winds 5-10 kts tonight pick back up to around 10 kts Saturday afternoon, then become light and variable Saturday evening as the center of high pressure moves over Florida. && .PRELIMINARY POINT TEMPS/POPS...
